SPECIFICATION forming part of Letters Patent N 0. 554,812, dated. February 18, 1896.

Application filed July 5,1895. Serial No. 554,918. (No model.)

To all whom it may concern.-

Be it known thatl, J AMES B. CLYNE, of Cleveland, in the county of Cuyahoga and State of Ohio, have invented certain new and useful Improvements in Machines for Making Screws, Nipples, &c. and I do hereby declare the following to be a full, clear, and exact description of the invention, such as will enable others skilled in the art to which it pertains to make and use the same.

My invention relates to improvements in lathes or metal-working machines more especially designed for making screws, nipples used in the attachment of the spokes of a bicycle-wheel to the wheel-rim, &c. and it consists in certain features of construction and combinations of parts hereinafter described, and pointed out in the claims. I

In the accompanying drawings, Figure 1 is a top plan of that portion of the machine that embraces my invention. Fig. 2 is a front side elevation of the same Fig. 3 is an elevation of a portion of the machine mostly in central vertical longitudinal section. Fig. 4 is a vertical section on line 4 4, Fig. 3. Fig. 5 is a vertical section on line 5 5, Fig. 3. Fig. 6 is a horizontal section on line 6 6, Fig. 3. Some features in Figs. 4, 5, and 6 are not in section. Fig. 7 is an end elevation of cam-wheel 0.

Referring to the drawings, A designates the work-holder, that is rotated in any approved manner. It is not considered necessary to show the mechanism for rotating the work, because the same forms no part of my present invention.

13 designates the tool-stock, that is preferably circular in cross-section, as shown in Figs. 1, 2, and 4, and is operatively mounted upon a horizontally-arranged shaft b, suitably supported from the stationary framework C of the machine" and arranged directly opposite to the Work-holder. In the case illustrated the tool-stock, mounted upon one end of shaft 17, has bearing in a box C rigid with framework C, and the shaft at or near its opposite end is supported as will hereinafter appear.

The tool-stock within its tool-bearing end is provided with any suitable number of pockets B for the reception of the tools required in the operation of the machine. The toolstock is therefore provided with as many pockets B as there are tools to be used for any Work for which the machine is adapted. The tool-stock in the case illustrated is provided with four tool-receiving pockets B and the work-holder is shown bearing a piece XV of metal to be bored and threaded internally and shaped externally to form a nipple suitable for use in securing the spoke of a bicycle-wheel to the wheel-rim.

I would here remark that work of the character indicated-such, for instance, as screws, nipples, &c.is made from wire or metallic rods, and the wire or rod is automatically fed through the work-holder while it is rotated with the holder.

In the manufacture of nipples for use in securing the spokes of bicycle-wheels to the wheel-rims three tools are requiredname1y, a drill for boring the screw-threaded hole in the stock of which the nipple is constructed, a tool for milling or shaping the blank externally, andanother tool for gaging the length of the nipple. The tool-stock in the case illustrated is, therefore, provided with the three tools indicated, and hence three of the toolreceiving pockets in the tool-stock are occupied, whereas the remaining tool-receiving pocket is empty. The tool-receiving pockets B, and consequently the tools of the toolstock, are arranged at suitable intervals about the axis of the tool-stock. Hence the arrangement of parts is such that the axis of the toolstock is located such a distance out of line with the axis of the work-holder that the tools of the tool-stock shall be adapted to be brought successively into engagement with the work to be operated upon. As already indicated, four tools are required for making some kinds of work for which the machine is designed, whereas less thanthat number of toolsas, for instance, three in the case illustrated are required in making other articles for the manufacture of which the machine is designed. It is, therefore, obvious that if, for

instance, the tool-stock has four tool-receiving pockets arranged equal distances apart, as in the case illustrated, and only three of said pockets are occupied by tools required to perform their functions successively, the tool-stock must be given a quarter-turn in bringing two of the tools into operative position and must be rotated a half-turn in order to bring the remaining tool into an operative position.

I11 Figs. 1 and 2 of the drawings the drill b of the tool-stock is shown in an operative position. The tool 1) for gaging the work occupies the tool-receiving pocket that is located diametrically opposite the pocket occupied by the drill and the milling or shaping tool Z) occupies one of the toolreceiving pockets between the pockets occupied by the gage and drill.

\Ve will suppose that, in the case illustrated, the gage first performs its function, that the milling or shaping tool is next called into requisition, and that the drills services are required for the last operation upon the work. The tool-stock will have been given a quarter-turn in bringing the milling or shapin g tool into operation after the gage has performed its function and will have been given another quarter-turn in bringing the drill into operation after the shaping or milling tool has performed its function, and must be given a half-turn in bringing the gage again into an operative position for the new blank to be operated upon after the drill has completed its operation upon the piece of work. Means is, therefore, provided for rotating the toolstoek intermittently and the distance required to bring the next succeeding tool into an operative position when the tool last opera-ting has performed its function.

D represents the driving-shaft of the machine, which shaft is arranged horizontally and at right angles to shaft 1), and is located a suitable distance below said shaft 1) and suitably supported from the stationary framework of the machine. Shaft D is provided with a drivingpulley (I, to which power is applied in any approved manner.

Driving-shaft D at its forward end is suitably intergeared, as at I), with a suitablysupported upright shaft E, that at its upper end is suitably intergeared, as at E, with a sleeve G that extends through and has hearing in a box C rigid with the stationary framework of the machine and is loosely mounted upon and affords bearing for shaft Z). Sleeve G, at the inner end of box C is provided with an annular shoulder G that engages said end of the box and prevents outward displacement of the sleeve, and said sleeve, at any suitable point between shoulder G and its inner extremity, is provided with an annular flange or collar G The one and relatively stationary member 11 of a toothed clutch is loosely mounted upon the inner end of sleeve G a suitable distance from the inner end of flange or collar i Clutch member H is provided with an external annular flange II, and a friction-ring I, composed of leather or any suitable material, is interposed between said flange and the opposing face of flange or collar G and said friction-ring is adjusted and held in the desired frictional engagement with the opposing faces of flanges G2 and II by means of any suitable number of screws J, having their heads engaging the outer side of flange G and extending through said flange into correspondingly-threaded holes formed within a metallic ring K that engages the periphery of flange II of the clutch memher and friction-ring I, and is flanged internally, as at K, to engage that side of flange If that faces away from the friction-ring. The movable member 71 of the clutch is rigidly mounted upon shaft 1) in any approved manner and is adapted to be brought into operative engagement with member II upon reciprocating the shaft in the required direction, and it will be observed that when operat-ive connection is established between the two members of the clutch the toolstock will be rotated. The reciprocation of the toolstock-bearing shaft in the direction required to move the movable clutch member toward the relatively stationary clutch member takes place quickly after the operation of the opcrating-tool; and I would here remark that the stock forming the blanks or work operated upon is, as already indicated, advanced as required during the aforesaid reciprocation of the tool-stock.

Mechanisms for automaticallyadvancing the work in lathes or metal-working machines are well understood by persons skilled in the art and do not need illustration in this application.

The means or mechanism employed for offecting the aforesaid reciprocation of the toolstock-bearing shaft comprises, preferably, the following: A sleeve L is rigidly mounted upon shaft 1) at the inner end of the toolstock, which sleeve upon its under side is preferably provided with a longitudinal groove or recess L that is engaged by the head at of a pin M extending downwardly into a boss C formed upon the stationary framework of the machine, and the engagement of the head of said pin with the side walls of the aforesaid recess or groove prevents circumferential displacement of the sleeve. Groove or recess L in the under side of sleeve L is long enough to accommodate the endwise movement of the sleeve during the reciprocation of the tool-stock-bearin g shaft.

The tool-stock prevents collar L from moving endwise of the supporting-shaft in the one direction, and a collar N, rigidly mounted upon the shaft at the other end of sleeve L, prevents endwise displacement of said sleeve in the opposite direction. Sleeve L upon its rear side is provided with a roller-bearing stud or lug Z, and the roller Z is adapted to be engaged by cams O suitably secured, preferably re1novab1y,to the periphery of the camwheel 0, that is operatively mounted upon shaft P, arranged a suitable distance rearward of and parallel with shaft 1) and suitably supported from the stationary framework of the machine. Shaft P is suit-ably intcrgeared with the driving-shaft D and prefer ably by means of a worm-wheel P operati vely mounted upon the cam-wheel-bearing shaft and meshing with a worm d'formed upon the driving-shaft. The working surfaces of cams 0 have such trend that they will slide the tool-stock-bearing shaft in the direction required to bring clutch member h into operative engagement with the companion clutch member H, and thereby establish operative connection between the tool-stock and driv ing-shaft and retain the two clutch members in operative engagement with each other until the required fractional turn has been given to the tool-stock. For instance, a half-turn, as has already been observed, must be given to the tool-stock in bringing one of the three tools shown into an operative position. Hence the cam O, employed for effecting said turn of the tool-stook,is necessarily constructed somewhat differently from the remaining cams O, employed for effecting a quarter-turn of the tool stock. WVheel O is provided with as many cams O as there are fractional turns to be given to the tool-stock during one complete rotation of the tool-stock-supporting shaft. In the case illustrated, therefore, cam-wheel O is provided with three cams 0 arranged at suitable intervals upon the periphery of said wheel. Cam-wheel O is also provided upon its periphery with another set of cams Q arranged at suitable intervals circumferentially of the wheel and adapted to engage roller Z and actuate the tool-stock-bearing shaft in the direction required to interrupt operative engagement with the two clutch members It and H, and thereby operatively disconnect the tool-stock from the driving-shaft, and the trend of the working surfaces Q of cams Qis such that the tool-stock shall be gradually advanced during the operation of the tools. WVheel O has, therefore, as many cams Q as there are cams O, and cams Q are so arranged relative to cams O that a cam Q shall have come into operative engagement with roller Z as soon as a cam Ohas performed its function.

To prevent circumferential displacement or vibration of the tool-stock during the operation of the tool, means for positively locking the tool-stock in the operative position of the tool is provided, and consists preferably of an upright boltRprovided at its upper end with a head R adapted to snugly engage longitudinal grooves or recesses B formed in the periphery and arranged longitudinally of the tool-stock, and a spiral spring R suitably confined upon bolt R acts in the direction to retain the bolt in its operative position. The tool-stock is provided with as many recesses or grooves 13 as there are tool-receiving pockets B and the arrangement of said grooves or recesses is such that one of them is opposite the head of the bolt in the operative position of any one of the tools with which the tool-stock is provided. BoltR extends downwardly through the adjacent portion of the stationary part of the machine, and,at its lower end, is operatively connected with the outer end of the vertically-tilting lever S that is fulcrumed at its opposite end, as at S, to a stationary member of the machine, and at any suitable point between its fulcrum and outer end supports an upright pin T that extends upwardly through the adjacent portion of the stationary part of the machine and, at its upper end, is provided with a roller T adapted to be engaged by an incline L formed upon sleeve L, and the trend of said incline and the arrangement of parts are such that the incline shall have come into engagement with roller T and shall have depressed pin T to actuate the engaging-lever S in the direction and to the extent required to render bolt R inoperative immediately before operative engagement is completed between the two clutch members it and H.

Clutch member 11 consists preferably of a disk provided upon its working face with radially-arranged teeth 10 arranged at suitable intervals upon said face and forming radially-arranged notches or recesses 11 between the teeth, and the movable clutch member it comprises preferablya pin 12 provided at one end with a head 13 that terminates at its outer end in a tooth 14 adapted to engage the aforesaid recesses 11 in the stationary clutch member, and consequently the tooth of the movable clutch member is arranged radially to the axis of the supporting-shaft, so that said tooth, when the movable clutch member is brought into operative engagement with the stationary clutch member,shall properly engage the opposing radially-arranged recess in said stationary member. The pin 12 has bearing in and has a limited movement endwise of a sleeve or collar 15 rigidly mounted upon shaft 19, which collar is provided with a horizontally-arranged hole 16 therethrough for the reception of the pin, and a stationary pin 17 that extends through a slot 18, formed in and extending longitudinally of the toothed pin 12, prevents circumferential displacement of said pin 12. A spiral spring 19 is confined upon pin 12 between the inner end of the toothed head of the pin anda shoulder 20 formed within said sleeve or collar near the slotted end of the pin. Slot 18 accommodates a limited longitudinal movement of pin 12, and spring 19 enables the movable clutch member to yieldingly engage the stationary clutch member and enables the movable clutch member to be pushed or crowded away from and by the stationary clutch member during the interval of interrupting operative connection between the clutch members. Also,by the construction hereinafter described, the stationary clutch member is capable of slipping upon the supporting and. actuating sleeve, as required, if

the complete withdrawal of bolt R from the tool-stock shall not have been effected when the movable clutch member has been brought into operative engagement with the companion or stationary clutch member.
